The boiler number three at Stora Enso Hyltebruk is a 100 MW gas/oil boiler, producing steam mainly for the paper mill but also for district heating during peak loads. The existing control logic will be replaced by new logic based on ÅF’s Balance+ control concept. The Balance+ control concept, developed by ÅF-Engineering in Finland, includes advanced adaptive control solutions, which provide higher efficiency, longer boiler life cycle and lower emissions than conventional control solutions.The project goals are maximal stability of the boiler and highest level of automation. ÅF is responsible for design, DCS utilization and commissioning of the new concept. ÅF’s Engineering Division units in Norrköping and Tampere carry out the project.
